Hello,
I want to make editor for editing function list, something like screenshot below. I would like to ask for an advice, what's the best approach to do this. I have idea to use GridView with self referencing, using some background class for representation of this structure, and massive cell parsing/formatting/validating for handling second column with parameters, validating different types of parameters, coloring of invalid values etc. Or, it's just two level structure, is it better to use "normal" hierarchy, main level for functions, and second level for different parameter? I haven't tried anything yet, just asking for advice for the best approach, I think it will take more time to do this.
And second question, I was playing a little with hierarchies some time ago, and most scenarios needed data binding for correct hierarchy. Is it possible to do self referencing without data binding?

Hi, Marian,
Self-referencing hierarchy in RadGridView is a possible approach for building the hierarchy illustrated in the screenshot. However, note that the columns in RadGridView share common data types in the cells that belong to a particular column. Hence, if you need to contain and edit different data types in a column, I believe that a better option would be to use RadPropertyGrid.
It is possible to add unbound data by using a RadPropertyStore filled with the desired PropertyStoreItems:
However, please have in mind that currently, the ExpandableObjectConverter is the appropriate solution for adding nested properties in RadPropertyGrid. Using TypeConverters is quite a flexible mechanism that RadPropertyGrid offers: https://docs.telerik.com/devtools/winforms/controls/propertygrid/type-converters
It would be nice to have a more flexible and easy approach, e.g. PropertyStoreItem.Items collection that allows you to add nested properties. We already have a feature request for similar functionality: https://feedback.telerik.com/winforms/1463121-radpropertygrid-add-possibility-to-add-child-items-for-a-propertystoreitem
I hope that the following KB article would be quite useful about covering your scenario: https://docs.telerik.com/devtools/winforms/knowledge-base/show-nested-collections-in-propertygrid
Please give it a try and see how it works for your case. If you need any further assistance please don't hesitate to contact me.
